Creatinase (creatine amidinohydrolase), an important medical enzyme, has been used for clinical diagnosis of renal function because of its high substrate specificity. Recently, we successfully cloned a NaN3-resistant creatinase encoding gene from Arthrobacter nicotianae. By optimizing the cultivation process, we realized its high-level expression in Escherichia coli. In this addendum, production of this NaN3-resistant creatinase in E. coli and future research were further discussed.
肌酸酶(肌酸脒基水解酶)是一种重要的医学酶,因其高底物特异性而被用于肾功能的临床诊断。最近,我们成功地从烟草节杆菌中克隆了一个耐NaN₃的肌酸酶编码基因。通过优化培养过程,我们实现了它在大肠杆菌中的高水平表达。在本附录中,进一步讨论了这种耐NaN₃肌酸酶在大肠杆菌中的生产及未来的研究。
